Founded as Foot-Ball Club Barcelona in 1899 by a group of Swiss, English, and Spanish footballers led by Joan Gamper, the club has become a symbol of Catalan culture and Catalanism, hence the motto "Més que un club" (English: More than a club). The official Barça anthem is the "Cant del Barça" written by Jaume Picas and Josep Maria Espinàs. Unlike many other football clubs, the supporters own and operate Barcelona. It is the world's second richest football club in terms of revenue, with an annual turn-over of €366 million. The club holds a long-standing rivalry with Real Madrid, and matches between the two teams are referred to as "El Clásico".
